Can a Self-Directed IRA Get a Mortgage? Yes — But Only One Kind.
Most people assume a retirement account can only buy real estate in cash. Not accurate — your Self-Directed IRA LLC can borrow. But it can use exactly one type of loan: a non-recourse loan, where the property is the only collateral, and without a personal guarantee.
That single rule shapes everything else — how much you can borrow, which lenders will talk to you, and whether the IRS taxes part of your rental income through something called UDFI. This article walks through all three, with the actual numbers, and shows you the one account type that can skip the UDFI tax entirely.
What "Non-Recourse" Actually Means
With a normal investment-property mortgage, the lender can come after you personally if the loan defaults. Inside an IRA, that's not permissible: a personal guarantee by you (a disqualified person) is itself a prohibited transaction under IRC § 4975, and the Tax Court confirmed it in Peek v. Commissioner (2013) — two investors personally guaranteed a loan their IRAs used, and the court treated their entire IRAs as distributed.
So the IRA borrows on a non-recourse basis. If the loan goes bad, the lender's only remedy is to take the property. They cannot touch you, your other IRA assets, or your personal accounts.
Because the lender carries more risk, non-recourse terms are more conservative than a personal mortgage. Typical 2026 non-recourse terms on a stabilized rental:
| Term | Typical non-recourse range |
|---|---|
| Down payment (from the IRA) | ~30%–40% minimum |
| Max loan-to-value | 60%–70% |
| Interest rate | ~1.5–2.5 points above a comparable personal mortgage |
| Personal guarantee | None — prohibited |
| Qualifies on | The property's cash flow, not your income |
How UDFI Works — With Real Numbers
Here's the part the financing decision turns on. When your IRA borrows, the IRS says the portion of your profit produced by the borrowed money isn't really tax-deferred retirement income — so it taxes that slice. That slice is Unrelated Debt-Financed Income (UDFI).
Let's run an actual example. Your IRA-owned LLC buys a $500,000 rental:
| | Amount | |
|---|---|
| Purchase price | $500,000 |
| IRA cash | $300,000 (60%) |
| Non-recourse loan | $200,000 (40%) |
| Debt-financed percentage | 40% |
| Net rental income (after operating expenses) | $24,000/yr |
The taxable UDFI starts at the debt-financed percentage of net income:
- 40% × $24,000 = $9,600 of gross UDFI.
But UDFI is calculated on net income, so the IRA still claims its share of the normal deductions, prorated by the same 40%. Depreciation is the big one: on a $400,000 building basis, straight-line over 27.5 years is ~$14,545/yr, and 40% of that is $5,818.
- $9,600 − $5,818 = $3,782 net debt-financed income
- Minus the $1,000 specific deduction = $2,782 actually taxable
- At trust tax rates, that's roughly $300–$400 in tax for the year.
On $24,000 of rental income, leverage cost the IRA a few hundred dollars in tax — while the borrowed $200,000 let the account control a $500,000 asset instead of a $300,000 one. For most investors the leverage wins. But you should run your numbers before you borrow, not after.
The Solo 401(k) Exemption (the real headline)
Now the fact that should be stated plainly, not hedged: a Solo 401(k) does not pay UDFI on debt-financed real estate. Under IRC § 514(c)(9), qualified retirement plans are exempt from UDFI on real-property acquisition debt (subject to the statute's conditions). Run the same $500,000 deal above inside a Solo 401(k) and the $2,782 is not taxed at all, and remains as tax-deferred income.
That is the single biggest reason a self-employed investor who plans to use leverage should look hard at a Solo 401(k) over an IRA:
| | Self-Directed IRA | Solo 401(k) | |
|---|---|---|
| Can borrow non-recourse | Yes | Yes |
| UDFI on leveraged real estate | Yes (Form 990-T) | No (§ 514(c)(9) exemption) |
| Who qualifies | Anyone with IRA-eligible funds | Self-employment income, no full-time employees |
| 2026 contribution ceiling | $7,500 ($8,600 if 50+) | $72,000 ($80,000 if 50+) |
If you have self-employment income and you intend to use leverage, the Solo 401(k) can legally erase the exact tax the IRA would owe.
Prohibited vs. Permitted: Financing Edition
| ✅ Permitted | ❌ Prohibited |
|---|---|
| IRA/401(k) takes a non-recourse loan | You (or any disqualified person) sign a personal guarantee |
| Lender qualifies the deal on property cash flow | You pledge personal assets as additional collateral |
| All debt service paid from the plan's bank account | You make a loan payment from personal funds when cash is tight |
| Reserves held inside the plan | You "spot" the property with personal money for repairs |
| Third-party property manager paid by the plan | You do the rehab yourself (sweat equity / a prohibited service) |
Meet David: A Worked Decision
David, 52, has $310,000 in a rollover IRA and a 1099 consulting business. He finds a $500,000 four-unit rental that nets $24,000/year. He has two paths:
- Self-Directed IRA route: he buys with $300K IRA cash + a $200K non-recourse loan. Cash flow is strong, but he files Form 990-T and pays ~$350 in UDFI tax annually.
- Solo 401(k) route: because he has self-employment income, he opens a Solo 401(k), rolls the IRA funds into the Solo (k), buys the same deal — and pays $0 UDFI under § 514(c)(9). He also gains the ability to contribute up to $80,000/year (with the 50+ catch-up) to keep funding the account.
Same property, same loan. The Solo 401(k) saved David the tax and gave him a far bigger contribution runway. The structure decision was worth more than the deal negotiation.
When You Don't Need Non-Recourse Financing
Leverage isn't mandatory. Skip it when:
- Your IRA can comfortably buy all-cash and you'd rather avoid UDFI altogether.
- The deal's cash flow is thin — adding debt service to a tight rental is how reserves run dry, and you cannot legally backfill from personal funds.
An all-cash IRA purchase has no UDFI, no 990-T, and no lender underwriting. For many first-time SDIRA investors, that simplicity is worth more than the leverage.
Frequently Asked Questions
Does my Self-Directed IRA have to use a non-recourse loan? If you need a loan, then yes. Any other loan would require a personal guarantee, which is a prohibited transaction under IRC § 4975 (Peek v. Commissioner).
How much will UDFI cost me? Only the debt-financed share of net income is taxable, after a prorated share of deductions (including depreciation) and a $1,000 exemption. On a 40%-leveraged rental netting $24,000, that's often only a few hundred dollars a year.
How do I avoid UDFI entirely? Either buy all-cash, or use a Solo 401(k), which is exempt from UDFI on real-property debt under IRC § 514(c)(9).
Who files the Form 990-T? Your IRA custodian files it on behalf of the IRA, using a separate EIN for the account. The tax is paid from IRA funds, never personal funds.
Can I pay the mortgage from my personal account if the rental is short on cash? No. Every dollar tied to the property — including debt service — must come from the plan. Backfilling with personal cash is a prohibited transaction.
